Load-Transient Considerations
The MAX8532 load-transient response graphs (see the
Typical Operating Characteristics
) show two compo-
nents of the output response: a DC shift in the output
voltage due to the different load currents, and the tran-
sient response. Increase the output capacitor
’
s value
and decrease its ESR to attenuate transient spikes.
Input/Output (Dropout Voltage)
A regulator
’
s minimum input/output voltage differential
(or dropout voltage) determines the lowest usable supply
voltage. In battery-powered systems, this determines
the useful end-of-life battery voltage. Because the
MAX8532 uses a P-channel MOSFET pass transistor, its
dropout voltage is a function of drain-to-source on-
resistance (R
DS(ON)
) multiplied by the load current (see
the
Typical Operating Characteristics
).
Calculating the Maximum
Output Power in UCSP
The maximum output power of the MAX8532 can be lim-
ited by the maximum power dissipation of the package.
Ascertain the maximum power dissipation by calculat-
ing the power dissipation of the package as a function
of the input voltage, output voltage, and output current.
The maximum power dissipation should not exceed the
package
’
s maximum power rating:
P = (V
IN(MAX)
- V
OUT
) x I
OUT
where:
V
IN(MAX)
= Maximum input voltage
P
MAX
= Maximum power dissipation of the package
(308mW for UCSP)
V
OUT
= Output voltage of OUT
I
OUT
= Maximum output current of OUT
P should be less than P
MAX
.
